Well, there are 0.25 quarts in a cup so if Krystal makes 18 cups of soup, she can serve 72 guests! because,
0.25 divided by 18 = 72! :)
5/8 * 4/5
5*4 20 1
----- = ----- = ---
8*5 40 2
5/8 * 4/5 = 1/2 or .5
<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.
cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41
Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.
(A) 0.10 feet
(B) 0.05 feet</span>
X=2 because 5^3=125 and there you are
